An auto-tracing tool of software. User can set breakpoints, this application will auto trace the target program and record the input and output of function call. Therefore, the software can help programmer analyse errors, process inside the target program, especially help the programmer analyse the sequences and parameters of the function call. Functions Recording input parameters and output result of the functions which are set breakpoints in the target program. Therefore, not need to compile the source code, you can monitor the input and output of functions.

Tracing Release version with mapfile. Debug some Anti-Debug program. Supporting debug version and release version, not need source code. Supporting tracing COM Interface. Supporting multithread. Through displaying sequence chart, easy get sequence relationship between all the threads. Supporting spying the parameters of function before and after the function is called. Supporting the function that the target program will dump CallStack when exception occurs. Supporting nested function call. Displaying the tracing result with tree structure, which can get the nested relationship of function call.

Supporting Plug-in technology. The user can define input format and output format and the number of parameters of every function. Plug-in technology is used to achieve the function of customizing monitoring result function. Please refer to the Sock_Spy program under the folder of Sample and refer to the sample code for the details. Supporting default monitoring design. The user can set the number of default monitoring parameters, under this condition, all functions have the same number of parameters and all parameters of function entry will be displayed. You can trace and monitor API without programming. Not need to know the prototype of the functions. All the API functions, including the opened functions that are called inside the DLL, can be monitored in deed.
